The United State Geographical Survey's Hawaiian Volcano Observatory said the lava flow extending southeast of Pu'u O'o toward the coastal plain on Kilauea's south flank reached the ocean about 1:12 a.m. local time.

The flow started May 24 and it's the first time it has traveled south down Kilauea and across the coastal plain since 2013.
USGS officials are warning those venturing out to view the spectacular display to use caution:
"There are additional significant hazards besides walking on uneven surfaces and around unstable, extremely steep sea cliffs," wrote the USGS in an update. "Venturing too close to an ocean entry exposes you to flying debris created by the explosive interaction between lava and water."
They warned that the new land created by the lava flow is unstable because it is "built on unconsolidated lava fragments and sand. This loose material can easily be eroded away by surf causing the new land to become unsupported and slide into the sea."

In addition, visitors should be careful to avoid the acidic plume that rises when the lava comes into contact with the water as the fine volcanic particles in the steam can irritate the skin, eyes and lungs."
